		<p>A new technique developed by researchers at Concordia University in Quebec could be used to unmask would-be anonymous emailers by sniffing out patterns in their writing style from use of all lowercase letters to common typos.</p>
		
	
		<p>Their research, published in the journal Digital Investigation, describes techniques that could be used to serve up evidence in court, giving law enforcement more detailed information than a simple IP address can produce.</p>

		<p>"In the past few years, we've seen an alarming increase in the number of cybercrimes involving anonymous emails," says study co-author Benjamin Fung, a professor of Information Systems Engineering at <a href="http://www.concordia.ca/now/what-we-do/research/20110307/identifying-anonymous-email-authors.php" target="_blank">Concordia University</a>, in a statement. "These emails can transmit threats or child pornography, facilitate communications between criminals or carry viruses."</p>
		
	
		<p>Of course some might be concerned that the technique could be used to reveal identities of whistleblowers or others who have legitimate reasons for sending emails via publicly available <a href="http://www.networkworld.com/news/2009/061709-free-tools-to-send-anonymous.html" target="_blank">tools for sending anonymous messages.</a></p>
		
	
		<p>The anonymous email-cracking technique devised by Fung and colleagues in cyber-forensics is to identify patterns in emails written by a subject, then filter out patterns found in emails of other suspects, narrowing it all down until only a unique "write-print" remains.</p>
		
	
		<p>Concordia researchers tested their system by putting it to use on over 200,000 emails from 158 employees of Enron, and were able to identify authors 80% to 90% of the time.</p>
